Answer:
44.55
Step-by-step explanation:
Internet said this: "Thus, a product that normally costs $ 81 with a 45 percent discount will cost you $ 44.55, and you saved $ 36.45. You can also calculate how much you save by simply moving the period in 45.00 percent two spaces to the left, and then multiply the result by $ 81 as follows: $ 81 x. 45 = $ 36.45 savings."
Hope this helps∞<3
Let me know if it right or wrong!
Answer: $44.55
Step-by-step explanation:

HELP PLZ THIS I NEED TO KNOW THIS
which table does not show a relation that is a function
-c+1 > 2 now this one
-c + 1 > 2
-c > 2-1 Move 1 to subtract.
-c > 1
c < -1 When the coefficient is negative, moving the negative to another side as changing the sign of Inequality to opposite.
Thus, the answer is c < -1

need help with this algebra problem ALG 2A
Answer:
If you are trying to simplify the expression, the answer is -14x^2+8x-37
Step-by-step explanation:
First, keep removing the parentheses.
(x-1)(2-x)+(x^2+5)(x-7) -x^2(x+6)
Next, try expanding the expression.
3x - x^2 - 2+ (x^2+5)(x-7)-x^2(x+6
3x-x^2-2+x^3-7x^2+5x-35-x^2(x+6
3x-x^2-2x^3-7x^2+5x-35-x^3-6x^2
Finally, simplify the expression.
-14x^2 8x-37

Find the slope of the following graph.
yaxis
(2.2)
(1.2)
Answer:
Y = 2
Step-by-step explanation:
Use the formula below to find the slope. Plug 0 in for X to find the y intercept. In this case there is no slope. Make sure next time to use commas , instead of periods . when writing coordinates.
What is the y-intercept of the graph?
Answer:
The y-intercept is -2.
Step-by-step explanation:
Look at the graph and see where the line crosses the y-axis.
Answer:
-2
Step-by-step explanation:
The y-intercept is defined as the point where the line crosses the y-axis. It can be negative or positive. In this picture, the line crosses the y-axis at the point -2.

Answer:
55
Step-by-step explanation:
m angle A and m angle C are equal sine two of those sides are equal. You would do 3x + 40 = x +50
You subtract x, leaving it to be 2x + 40 = 50
Subtract the 40, leaving it be 2x = 10
Divide both sides by 2, which leaves x = 5
and then you would do 3(5) + 40, which is 55

Which expression is equivalent to 8x - 12y + 32?
A. 16(0.5x 4y +32)
B. 16(0.5x - 0.75y + 32)
C. 16(0.5x - 0.75y + 2)
D. 16(0.5x + 4y +2)
Answer:
It's the third
16(0.5x - 0.75y +2)
Step-by-step explanation:
You just divide everything by 16
8x/16= 1/2x=0.5x
-12y/16 = -3/4x=-0.75x
32/16=2

A new shopping mall records 120 total shoppers on their first day of business. Each day after that, the number of shoppers is 10, percent more than the number of shoppers the day before. What is the total number of shoppers that visited the mall in the first 7 days?
Answer:
1138
Step-by-step explanation:
From the information given:
We can represent it perfectly in an exponential form:
[tex]m = p(q)^x[/tex]
where;
p = initial value = 120
q = base of the exponential form
q = 1 + r
here; r = rate in decimal = 10% = 0.1
Then q can now be = 1 + 0.1 = 1.1
Replacing it into the exponential form, we get:
[tex]m = 120(1.1)^x[/tex]
where;
x = number of days and m = number of shoppers
Thus:
For the first day:
[tex]m = 120(1.1)^x[/tex]
m = 120
For the second day:
[tex]m = 120(1.1)^1[/tex]
m = 132
For the third day:
[tex]m = 120(1.1)^2[/tex]
m = 145.2
For the fourth day
[tex]m = 120(1.1)^3[/tex]
m = 159.72
For the fifth-day
[tex]m = 120(1.1)^4[/tex]
m = 175.692
For the sixth-day
[tex]m = 120(1.1)^5[/tex]
m = 193.2612
For the seventh-day
[tex]m = 120(1.1)^6[/tex]
m = 212.58732
Thus; the total numbers of shoppers for the first 7 days is:
[tex]= 120+ 132 + 145.2 + 159.72 + 175.692+193.2612+212.58732[/tex]
= 1138.46052
≅ 1138

The amount of paper that the copy shop used this month was a 25% increase of the amount of paper they used last month. This month, there were 78 copies made. How many copies were made last month?
Answer:
98 copies
Step-by-step explanation:
25% of 78 is 19.5
19.5 + 78 = 97.5
Because there can't be half of a copy we round up based on the decimal. Therefore the answer would 98 copies.

tan 45 * cos 45 + tan 30 * tan square 60
Answer:
Regroup Terms: cos 45 tan 45x + tan^2 tan 30x, 60
Answer:
[tex]\frac{1}{\sqrt{2}}+\frac{3}{\sqrt{3}}[/tex] , by the way, the simplified is [tex]2.439157589[/tex]
Step-by-step explanation:
I included a chart so next time you don't need to worry
tan( 45 degrees) = 1cos( 45 degrees) = [tex]\frac{1}{\sqrt{2}}[/tex] tan( 30 degrees) = [tex]\frac{1}{\sqrt{3}}[/tex] tan squared (60 degrees) is the same as saying square the answer of tan (60 degrees). So tan( 60 degrees) = [tex]\sqrt{3}[/tex] , so squareWhich function is represented in the graph shown?
A)

Point-slope form
Complete the point-slope equation of the line through (-4, 8) and (4,4).
Use exact numbers.
WHOEVER ANSWERS RIGHT GETS BRAINIST
There are actually two correct answers, one of them is y-4=-0.5(x-4)
First of all, the slope-intercept that can be derived from the points (-4,8) and (4,4) is y=[tex]-\frac{x}{2} +6[/tex], with -0.5 being the slope. To bring this to point-slope form, you must signify the slope and the coordinate intersection. Since there are two coordinates, there are actually two point-slope equations.
